GIT-WHATCHANGED(1)                               Git Manual                               GIT-WHATCHANGED(1)



NAME
       git-whatchanged - Show logs with difference each commit introduces

SYNOPSIS
       git whatchanged <option>...


DESCRIPTION
       Shows commit logs and diff output each commit introduces. The command internally invokes git rev-list
       piped to git diff-tree, and takes command line options for both of these commands.

       This manual page describes only the most frequently used options.

OPTIONS
       -p
           Show textual diffs, instead of the Git internal diff output format that is useful only to tell
           the changed paths and their nature of changes.

       -<n>
           Limit output to <n> commits.

       <since>..<until>
           Limit output to between the two named commits (bottom exclusive, top inclusive).

       -r
           Show Git internal diff output, but for the whole tree, not just the top level.

       -m
           By default, differences for merge commits are not shown. With this flag, show differences to that
           commit from all of its parents.

           However, it is not very useful in general, although it is useful on a file-by-file basis.

       --pretty[=<format>], --format=<format>
           Pretty-print the contents of the commit logs in a given format, where <format> can be one of
           oneline, short, medium, full, fuller, email, raw and format:<string>. See the "PRETTY FORMATS"
           section for some additional details for each format. When omitted, the format defaults to medium.

           Note: you can specify the default pretty format in the repository configuration (see git-config(1)). gitconfig(1)).
           config(1)).

       --abbrev-commit
           Instead of showing the full 40-byte hexadecimal commit object name, show only a partial prefix.
           Non default number of digits can be specified with "--abbrev=<n>" (which also modifies diff
           output, if it is displayed).

           This should make "--pretty=oneline" a whole lot more readable for people using 80-column
           terminals.

       --no-abbrev-commit
           Show the full 40-byte hexadecimal commit object name. This negates --abbrev-commit and those
           options which imply it such as "--oneline". It also overrides the log.abbrevCommit variable.

       --oneline
           This is a shorthand for "--pretty=oneline --abbrev-commit" used together.

       --encoding[=<encoding>]
           The commit objects record the encoding used for the log message in their encoding header; this
           option can be used to tell the command to re-code the commit log message in the encoding
           preferred by the user. For non plumbing commands this defaults to UTF-8.

       --notes[=<ref>]
           Show the notes (see git-notes(1)) that annotate the commit, when showing the commit log message.
           This is the default for git log, git show and git whatchanged commands when there is no --pretty,
           --format nor --oneline option given on the command line.

           By default, the notes shown are from the notes refs listed in the core.notesRef and
           notes.displayRef variables (or corresponding environment overrides). See git-config(1) for more
           details.

           With an optional <ref> argument, show this notes ref instead of the default notes ref(s). The ref
           is taken to be in refs/notes/ if it is not qualified.

           Multiple --notes options can be combined to control which notes are being displayed. Examples:
           "--notes=foo" will show only notes from "refs/notes/foo"; "--notes=foo --notes" will show both
           notes from "refs/notes/foo" and from the default notes ref(s).

       --no-notes
           Do not show notes. This negates the above --notes option, by resetting the list of notes refs
           from which notes are shown. Options are parsed in the order given on the command line, so e.g.
           "--notes --notes=foo --no-notes --notes=bar" will only show notes from "refs/notes/bar".

       --show-notes[=<ref>], --[no-]standard-notes
           These options are deprecated. Use the above --notes/--no-notes options instead.

       --show-signature
           Check the validity of a signed commit object by passing the signature to gpg --verify and show
           the output.

PRETTY FORMATS
       If the commit is a merge, and if the pretty-format is not oneline, email or raw, an additional line
       is inserted before the Author: line. This line begins with "Merge: " and the sha1s of ancestral
       commits are printed, separated by spaces. Note that the listed commits may not necessarily be the
       list of the direct parent commits if you have limited your view of history: for example, if you are
       only interested in changes related to a certain directory or file.

       There are several built-in formats, and you can define additional formats by setting a pretty.<name>
       config option to either another format name, or a format: string, as described below (see git-config(1)). gitconfig(1)).
       config(1)). Here are the details of the built-in formats:

       •    oneline

               <sha1> <title line>

           This is designed to be as compact as possible.

       •    short

               commit <sha1>
               Author: <author>

               <title line>

       •    medium

               commit <sha1>
               Author: <author>
               Date:   <author date>

               <title line>

               <full commit message>

       •    full

               commit <sha1>
               Author: <author>
               Commit: <committer>

               <title line>

               <full commit message>

       •    fuller

               commit <sha1>
               Author:     <author>
               AuthorDate: <author date>
               Commit:     <committer>
               CommitDate: <committer date>

               <title line>

               <full commit message>

       •    email

               From <sha1> <date>
               From: <author>
               Date: <author date>
               Subject: [PATCH] <title line>

               <full commit message>

       •    raw

           The raw format shows the entire commit exactly as stored in the commit object. Notably, the
           SHA-1s are displayed in full, regardless of whether --abbrev or --no-abbrev are used, and parents
           information show the true parent commits, without taking grafts nor history simplification into
           account.

       •    format:<string>

           The format:<string> format allows you to specify which information you want to show. It works a
           little bit like printf format, with the notable exception that you get a newline with %n instead
           of \n.

           E.g, format:"The author of %h was %an, %ar%nThe title was >>%s<<%n" would show something like
           this:

               The author of fe6e0ee was Junio C Hamano, 23 hours ago
               The title was >>t4119: test autocomputing -p<n> for traditional diff input.<<

           The placeholders are:

           •    %H: commit hash

           •    %h: abbreviated commit hash

           •    %T: tree hash

           •    %t: abbreviated tree hash

           •    %P: parent hashes

           •    %p: abbreviated parent hashes

           •    %an: author name

           •    %aN: author name (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           •    %ae: author email

           •    %aD: author date, RFC2822 style

           •    %ar: author date, relative

           •    %at: author date, UNIX timestamp

           •    %ai: author date, ISO 8601 format

           •    %cn: committer name

           •    %cN: committer name (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           •    %ce: committer email

           •    %cE: committer email (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           •    %cd: committer date

           •    %cD: committer date, RFC2822 style

           •    %cr: committer date, relative

           •    %ct: committer date, UNIX timestamp

           •    %ci: committer date, ISO 8601 format

           •    %d: ref names, like the --decorate option of git-log(1)

           •    %e: encoding

           •    %s: subject

           •    %f: sanitized subject line, suitable for a filename

           •    %b: body

           •    %B: raw body (unwrapped subject and body)

           •    %N: commit notes

           •    %GG: raw verification message from GPG for a signed commit

           •    %G?: show "G" for a Good signature, "B" for a Bad signature, "U" for a good, untrusted
               signature and "N" for no signature

           •    %GS: show the name of the signer for a signed commit

           •    %GK: show the key used to sign a signed commit

           •    %gD: reflog selector, e.g., refs/stash@{1}

           •    %gd: shortened reflog selector, e.g., stash@{1}

           •    %gn: reflog identity name

           •    %gN: reflog identity name (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           •    %ge: reflog identity email

           •    %gE: reflog identity email (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           •    %gs: reflog subject

           •    %Cred: switch color to red

           •    %Cgreen: switch color to green

           •    %Cblue: switch color to blue

           •    %Creset: reset color

           •    %C(...): color specification, as described in color.branch.* config option; adding auto, at
               the beginning will emit color only when colors are enabled for log output (by color.diff,
               color.ui, or --color, and respecting the auto settings of the former if we are going to a
               terminal).  auto alone (i.e.  %C(auto)) will turn on auto coloring on the next placeholders
               until the color is switched again.

           •    %m: left, right or boundary mark

           •    %n: newline

           •    %%: a raw %

           •    %x__: print a byte from a hex code

           •    %w([<w>[,<i1>[,<i2>]]]): switch line wrapping, like the -w option of git-shortlog(1).

           •    %<(<N>[,trunc|ltrunc|mtrunc]): make the next placeholder take at least N columns, padding
               spaces on the right if necessary. Optionally truncate at the beginning (ltrunc), the middle
               (mtrunc) or the end (trunc) if the output is longer than N columns. Note that truncating only
               works correctly with N >= 2.

           •    %<|(<N>): make the next placeholder take at least until Nth columns, padding spaces on the
               right if necessary

           •    %>(<N>), %>|(<N>): similar to %<(<N>), %<|(<N>) respectively, but padding spaces on the left

           •    %>>(<N>), %>>|(<N>): similar to %>(<N>), %>|(<N>) respectively, except that if the next
               placeholder takes more spaces than given and there are spaces on its left, use those spaces

           •    %><(<N>), %><|(<N>): similar to % <(<N>), %<|(<N>) respectively, but padding both sides
               (i.e. the text is centered)

           Note
           Some placeholders may depend on other options given to the revision traversal engine. For
           example, the %g* reflog options will insert an empty string unless we are traversing reflog
           entries (e.g., by git log -g). The %d placeholder will use the "short" decoration format if
           --decorate was not already provided on the command line.

       If you add a + (plus sign) after % of a placeholder, a line-feed is inserted immediately before the
       expansion if and only if the placeholder expands to a non-empty string.

       If you add a - (minus sign) after % of a placeholder, line-feeds that immediately precede the
       expansion are deleted if and only if the placeholder expands to an empty string.

       If you add a ` ` (space) after % of a placeholder, a space is inserted immediately before the
       expansion if and only if the placeholder expands to a non-empty string.

       •    tformat:

           The tformat: format works exactly like format:, except that it provides "terminator" semantics
           instead of "separator" semantics. In other words, each commit has the message terminator
           character (usually a newline) appended, rather than a separator placed between entries. This
           means that the final entry of a single-line format will be properly terminated with a new line,
           just as the "oneline" format does. For example:

               $ git log -2 --pretty=format:%h 4da45bef \
                 | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
               4da45be
               7134973 -- NO NEWLINE

               $ git log -2 --pretty=tformat:%h 4da45bef \
                 | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
               4da45be
               7134973

           In addition, any unrecognized string that has a % in it is interpreted as if it has tformat: in
           front of it. For example, these two are equivalent:

               $ git log -2 --pretty=tformat:%h 4da45bef
               $ git log -2 --pretty=%h 4da45bef


EXAMPLES
       git whatchanged -p v2.6.12.. include/scsi drivers/scsi
           Show as patches the commits since version v2.6.12 that changed any file in the include/scsi or
           drivers/scsi subdirectories

       git whatchanged --since="2 weeks ago" -- gitk
           Show the changes during the last two weeks to the file gitk. The "--" is necessary to avoid
           confusion with the branch named gitk
